APPARATUS FOR CARBONATING LIQUIDS.

SPECIFICATION forming part of Letters Patent No. 603,031, dated April 26, 1898. Application filed May 15, 1897. Serial No. 636,606. (No model.)

To all whom it may concern.-

Be it known that I, Or'ro WALDEMAR Acn- ERMAN, a citizen of the United States, and a resident of New York city, in the. county of New York and State of New York, have invented certain new and useful Improvements in Apparatus for Garbonating Liquids, of which the following is a specification.

My invention relates to carbonatin g liquids by causing the carbonating-gas to meet the fluid issuing in finely-divided spray from a diffusing medium; and it consists of an improved construction and arrangement of the apparatus, as hereinafter described, reference being made to the accompanying drawings, in which- Figure 1 is a plan view of the apparatus employed. Fig. 2 is partly a side elevation and partly a sectional elevation, and Fig. 3 is a detail of the liquid-dividing and gas-mixing device in sectional elevation and on a larger scale than represented in the other figures.

A represents a retort containing the carbonated gas under high pressure and in liquid form.

a represents a strong hollow horizontal cylinder into which water or other liquids to be carbonated is supplied from any source, as from the water-service main, through a supply-pipe b, in which is a stop-cock c to close off the supply-pipe when the cylinder is charged.

('5 is a pipe connecting retort A with cylinder a for admitting the gas thereto.

e is a pressure-regulating valve in the pipe (1, it being necessary to reduce the pressure in cylinder 0. considerably below that of the retort, and f is a stop-cock in pipe cl to shut ed the gas entirely when cylinder a is to be replenished. V

g is another horizontal hollow cylinder similar to a and arranged in any suitable relation for cooperation therewith. The two cylinders are connected by the gas-pipe h, which is a branch of pipe cl, for admitting gas into cylinder g. It is provided with a cock g to prevent full pressure in cylinder and said cylinders are also connected by the water-pipe 11 and the water distributing or atomizing device j for transferring the water from a to g and at the same time atomizing it for intimate admixture of the carbonated gas with the water. A drop-pipe 7c (dotted in Fig. 1) extends from pipe '11 to the bottom of cylinder a for delivering the water by means of gas-pressure on the surface of the water.

The mixer or pcrcolator is practically a lilter consisting of bell-shaped case j, with the top of which the water-pipe i connects and containing the inverted porous cup Z, capped at the lower end by the cover m having a nozzle n, detachably connected with the upper side of cylinder g, so that gas in the upper portion of cylinder 9 will rise freely into the chamber of the percolating-cup. The case'j is also detachably connected with pipe 2', so that the percolator can be readily detached for opening and cleaning it, the lower head of the case being detachable for this purpose. From cylinder 9 a discharge-pipe 0, having a drop extension 19 within said cylinder, leads to a cooling-coil q in a suitable box 5, and thence to the tap ifor drawing the carbonated water.

In the operation of the apparatus the cylinder a is first charged full of water and the supply is shut off by cock 0. Then gas is admitted from retort A through the reducingvalve 6 and also into cylinder 91 through the equalizing-pipe h, but subject to limitation of pressure in said cylinder g below the pressure in a lay-cock g. YVater is then forced out of cylinder a through pipe '5 and through the percolator Z, where it meets in its finelydistributed condition the gas within the chamber of the percolator and is thereby thoroughly mixed with the gas and descends into the chamber of cylinder 9 in a highly-carbonated condition, and from said chamber it is drawn as required through the tap i, being forced thereto by the pressure of gas in said cylinder g. Each draft reduces the pressure in cylinder g and the percolating action proceeds according as the pressure in the percolator is less than'on its exterior. Should the action be sluggish owing to equal or nearly equal pressure inside and outside of the percolator, the cock g may be closed from time to time for greater inequalities of pressures. If desired, an automatic pressure-reducing valve may be employed instead of a stop-cock.

By the use of the cock g for regulating the pressure in cylinder g it is more feasible to vary the pressure and adjust it as maybe-re of the carbonated liquid, and the pipe connecting the liquid-receiving cylinder with the percolator, said pipe having the drop extension in said cylinder substantially as described.
